ECU immobilizer question for 2001 gsr

[speedminded]

Ok i have another question about my ecu/ignition/gauge cluster,ok so my teg is a 2001 and the 2001 gauge cluster has the little green key that flashes when i start and turn the car off because of the chip in the key.Before i replaced the gauge cluster with this one i tried one that didnt have that little green flashing key and the gauge cluster wouldnt work and i had to get one i guess that was suited properly for the immobilizer in my ecu.Well now that I'll be putting a different swap in with a different ecu am i going to have to mess with the ignition because of the way the key is set up?And am i going to have to change out my gauge cluster?And what about the wiring that connects to my ecu will i have to change that too? or alter it in any way because of the wiring being slightly different for the chip in the key/gauge cluster setup?

whoa, you're thinking about this way too hard.

What swap are you doing first of all? What ECU?

If you use an OBD1 or OBD2a ECU then you shouldn't have to worry about anything. You'll just need a conversion harness from OBD2b to whatever ECU you run.

I'm running a '98 ITR ECU in my '01 GS-R w/ B18c5 so had to use an OBD2b to OBD2a conversion harness. Zero issues with gauge cluster not working.

and no issues with using your chipped key/ignition?And I'm not sure of the swa[ i just wanted to make sure i wasnt going to run into any problems
